Question 5 What effect would a decrease in temperature have on pressure, assuming that volume (T) and moles of gas (n) are kept constant? Group of answer choices Pressure would decrease. Pressure would stay the same regardless of a change in temperature. Pressure would increase Question 6 Which temperature scale has NO negative values? Group of answer choices Farenheit Digital Kelvin Celcius Question 7 Calculate the number of moles of gas with a volume of 35.0 L at a temperature...
if someone could show me how to do 5 of these questions, that would be great. thanks Boyle's Law Name Directions: Use Boyle's Law to answer the following questions: Assume constant temp, number of moles and containers can withstand all changes in pressure. 5.50 L of Ne is under 1.05 atm. If the container volume is increased to 8.50 L calculate the new pressure. A 20.0 L tank has a pressure of 3.55 atm. If the pressure is lowered to...
